Abstract
Inter-integrated circuit input circuitry includes a pull-up current circuit and an input circuit. The input circuit includes an output inverter, an input inverter, and a pull-up circuit. The pull-up circuit is coupled to an input of the input inverter, and includes a pull-up transistor and a cascode transistor. The pull-up transistor is coupled to the input of the input inverter. The cascode transistor is coupled to the pull-up current circuit and the pull-up transistor, and configured to isolate the pull-up transistor from capacitance of a conductor coupled to the pull-up current circuit and the input circuit.
